sorry, you may have misunderstood....
not mapping for the Haldex.... imeant mapping for the engine in general... so the engine runs to its full potential?
right i thought it was a bit strange may have mis read it wrong ,(easy done with me lol)
regards the engine , i never had the engine harness/loom or ecu so i thow a quick one togther and used a megasquirt 1 v3 standalone with wideband inovate for the tuning , as i did a bit of re search into these engines , and theres only mk3 2.8 and the mk4 2.8 12v/24v that were but with forged cranks and strong internals , as the 3.2/3/6 v6 have problems with timing chain failure and cranks snapping , plus the block walls are a lot thicker too ,
so with a good tuine these babys can handle 600bhp , as these engines were firsly built as a deisal with strong rods , then changed on the production line to petrol , long u you lower compression its all fine , i know a lot of people go to exspense in buying custon rods and pistons , but i ask myself why?as i first did a test on a mk3 2.8 vr6 stock engine and gearbox , just thow a turbo kit on it , and standalone to tune , only got to 10psi and engine compression was too high , so cut and made a headspacer to lower it to 8.5.1 ratio , totaly differnert , i got 400bhp and it blow the gearbox in 3rd gear , nice bang crunch
that was at 27psi of boost , engine had no problems at all , so after a bit of messing we thow the later 02m gearbox on it 6speed , just used 2wd , as these take 500bhp , then testing it , great short gear ratios runing 30psi of boost , all was well keeping the afr table 12.1 , the only bad thing the 02m run a crap dual mass flywheel , which dont like hp , and to convert to single mass , u need a bank lone lol , so in a word , with good tuning these are good engines for outputs in terms of power
also the mk3 vr6 turbo was runing 215 35 18 tyres and at 100mph the tyres would hold to the road , gives u an idea the amount of torque and power they produce
